What model of under the desk elliptical did you get?
The cubii jr2, I bought one during the black friday sales, bought a different type for my mother but it was too heavy for her to move so I gave her mine, gave that one to my mother in law and bought the jr2 to replace it.
My 86 year old mother has been using one for a couple weeks now and she’s seeing a major improvement in her leg strength, be advised this crazy woman goes to the gym every other day still.
I can’t say enough about under desk ellipticals, as long as they’re used they work miracles.
